ART 013 DISTILLIN'G EASILY-DECOMPOSABLE MATERIALS. Application filed December 30, 1922, Serial No. 609,886. Renewed August 7, 1926.

The present invention'relates to the art of release connections being provided. A distillation, particularly vacuum distillation, manometer conection 22 is provided, at a conand will be fully understood from the folvenient location above the foaming level, and lowing description,reference being had also thermometers may be located where desir- 6 to the accompanying drawing which repreable.
